EYEGLASSES.

Specification of Letters Patent.

Patented Nov 23, 1909.

Application filed December 19, 1908. Serial No. 468,268.

To all whom it may concern:

Be it known that I, FREDERICK HAMILTON, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specific-at-ion.

My invention relates particularly to the nose guards of eyeglasses and similar articles and has for its essential objects a structure which shall provide a resilient engagement with the nose of a clinging character, and an auxiliary clinging agent which shall be cheap and easily applied, or easily removed after deterioration.

A further object is to provide a bearing or firm backing for the resilient member which shall prevent excessive distention of the latter; and further, to provide a form of guard readily adapted to lateral adjustment.

Other objects will be hereinafter mentioned in the description of the invention, and form the subjectmatter of claims.

In the accompanying drawings which form a part of this specification, and in which like reference letters indicate like parts throughout the views, Figure l is a rear elevation of a pair of eyeglasses embodying my invention, Fig. 2, a section of the same on line a; so of Fig. 1, Fig. 3, an outer side elevation of my novel guard, Fig. 4, a detail view of the tube section before application to the guard, Fig. 5, an inner side elevation of the guard, and Fig. 6, a section of the guard on line y y of Fig. 1.

In the drawings, A are the lenses, B the straps, C the bridge or spring, and D the boxes of an ordinary pair of eyeglasses in connection with which my novel guard may be conveniently used; but it will be understood that the particular form of the above enumerated parts is not essential.

The guard in detail comprises a nearly vertical flattened body or plate, E, provided with a broad, stiff, upper portion, and a narrower lower portion, 5, bent edgewise of the stock to form a reentrant spring loop, F, and continued upwardly to form a flat spring arm, G, lying in a plane substantially parallel with the body, E. The upper end of the arm, G, is broad as at g, and is preferably provided with concaved edges or reduced portions as at g g.

In Fig. a is shown a section cut from a soft rubber tube. This elastic cylindrical section, H, is stretched over the upper end, 9, of the resilient arm, G, which it surrounds, and is held against accidental displacement by the seat formed by the reduced portions, 9 9'. These concavities also have a tendency to raise the intermediate portions of the bands, H, and better adapt them as pad surfaces.

Integral with the body, E, and extending therefrom midway its length is an upwardly curved attaching arm, I, terminating in the squared end portion, 2', and in this instance provided with the usual opening, J, to receive the fastening screw, K. But the shape of the portion, 2", or the presence of the opening, J, is not essential.

The guard is mounted in any convenient or usual manner. The arms, G, form a resilient seat for the nose, and their tension may be readily increased or diminished by bending with pliers the lower portions of the arms, G, either away from or toward their bodies, E. The stiff portions of the latter furnish an efiective stop to the excessive outward travel or distention of the arms, G and shield portions of the bands, H, which are intermediate the two plates from observation. Slipping of the guard caused by perspiration, sudden movement, inclination, or the like is insured against further by the location and clinging character of the bands, H. These are made readily removable, and from a common, inexpensive article of commerce, to render it possible to easily substitute new bands after a period of use sufficient to charge them with dirt or bodily cxudations.

.Vhat I claim is,

1. A nose guard for eyeglasses composed of flat material and comprising a body and an attaching arm extending at substantially a right angle therefrom near its midlength, a spring loop extending from the junction of said arm with the body and bent edg wise of the material with its side portions out of the plane of the body, and a spring arm extending from said loop and disposed in a plane parallel with and disposed within the area of said body portion.

2. A nose guard for eyeglasses composed of flat material and comprising a body and an attaching arm extending at substantially a right angle therefrom near its midlength, a spring loop extending from the junction of said arm with the body and bent edgewise of the material with its side portions out of the plane of the body, and a spring arm extending from said loop and disposed in a plane parallel with and disposed within the area of said body portion, the opposite edges of said spring arm being provided with concavities.

3. A nose guard for eyeglasses composed of flat material and comprising a body and an attaching arm extending at substantially.

a right angle therefrom near its midlength, a spring loop extending from the junction of said arm with the body and bent edgewise of the material with its side portions out of the plane of the body, and a spring arm extending from said loop and disposed in a plane parallel with and disposed within the area of said body portion, the opposite edges of said spring arm being provided with concavities and an elastic band seated in said concavities and disposed within the area of the body portion and bearing thereagainst.

l. A nose guard for eyeglasses composed of flat material and comprising a body and an attaching arm extending at substantially a right angle therefrom near its midlength a spring loop extending from the junction of said arm with the body and bent edgewise of the material with its side portions out of the plane of the body, and a spring arm extending from said loop and disposed in a plane parallel with and disposed within the area of said body portion, the opposite edges of said spring arm being provided with concavities and an elastic band seated in said concavities and disposed within the area of the body portion and bearing thereagainst,

said band by reason of said concavities having its portions intermediate the concavities raised to form pad surfaces.

5. In a nose guard, the combination with the attaching arm, of a body plate integral therewith and provided at its end with a spring loop edgewise of the body plate and to one side of the plane of the body, a plate integral with the loop and parallel to the body plate, and an elastic band upon the second plate having a portion thereof intermediate the two plates and shielded by the body plate.

6. As an improved article of manufacture, a nose guard comprising in a single element a substantially vertical flattened plate provided with a broad stiff upper portion, a narrower lower portion bent edgewise of the body to form a spring loop to one side of the plane of the body with the adjacent ends crossing at the junction of the body with the loop and an upwardly continued flat spring arm lying in a plane substantially parallel with said plate, the free end of said arm being broadened with its edges concaved,-and an upwardly curved attaching arm extending substantially midway of the length of said plate, and an elastic band embracing the free end of said spring arm and received within the concaved portions thereof.

In testimony whereof I have affixed my signature in presence of two witnesses.
